v HOOD FOR PNEUMATIC STACKERS.

SPECIFICATION forming part of Letters Patent N 0. 771,118, dated. September 2'7, 1904. Application filed April 18, 1904. Serial No. 203,695. (No model.)

To all whom it may concern.-

Be it known that we, FRANK BEOHTEL and EDWARD M. HAGAR, citizens of the United States, residing at Anchor, in the county of of Illinois, have invented new and useful Improvements in Hoods for Pneumatic Stackers, of which the following is a specification.

Our invention relates to improvements in threshing-machines, more especially hoods for the stacker attachments thereof.

Said invention has for its object to effect the advantageous delivery of the refuse-such as the straw, chafi, cheat, &c.fed with the grain into the threshing-machine and eliminated thereby with the view to properly dispose or form the same into a pile or stack below and to abate or wholly obviate the otherwise scattering action of the blower or fanast upon said straw, chaff, and accompanying dust as delivered from the machine.

The nature of said invention consists of the detailed structural features substantially as hereinafter more fully disclosed, and particularly pointed out by the claims.

In the accompanying drawings, Figure 1 is a broken-away view in side elevation of one form of a stacker attachment of a threshingmachine with our invention applied thereto. Fig. 2 is a vertical section of said invention. Fig. 3 is a horizontal section thereof produced on the line of the receiving or intake tube. Fig. 4 is a plan view of the same.

In the carrying out of our invention we hood or collector 1 for the delivery end of the stacker attachment or tube 2 of a threshingmachine, cylindric in general outline, with a lateral circular bulging portion 1, joining at 0 its upper edge the flat head thereof and at its lower edge a short tubular terminal or skirt 1" of less diameter or cross-section than said portion 1, presently again referred to. Said hood has communicating therewith a lateral 5 inlet or intake tube 3, arranged so as to deliver thereinto in a line tangentially to the axial plane thereof, as shown, so that the incoming substance is directed or delivered laterally upon the inner concaved surface or wall of the bulged portion 1 cross-sectional area of said hood, whereby said substance is caused by the feeding-blast to follow said wall in an arcuate path or di rection before its final delivery. This will greatly reduce the force or movement of said substance en route to its point of delivery and effect such delivery devoid of a whirling or circling action, as would otherwise be the case, thus preventing the scattering of the straw, chaff, and cheat, together with the attendant dust, resulting in the consequent even or uniform stacking of the same and preventing the flying thereof upon the attendants of the machine to their great discomfort and interference with. the eflec tive execution of their work.

The inlet or intake tube 3 is pivoted at its receiving end upon tube-section 2, suitably secured or inserted into the outer end of the stacker-tube, the former being reduced or curtailed upon opposite forward edges in curved lines, as at 3 to provide for the angular adjustment of the hood according to the direction in which it may be desired to deliver the substance or material passing therethrough, as will more fully appear later.

The outlet-tube 1 has upon its inner surface a plurality of vertical or radial plates or partitions 3, preferably tapered toward their upper ends and arranged equidistantly apart, said partitions dividing up and aiding to effectively counteract the circling or whirling action of the blast, with the substances being delivered thereby, and also to center the delivery of the latter in properly disposing of the same, as in building the stack therefrom. Said outlet or deliverytube has a much greater or diameter than has the intake or inlet tube to further aid, as will be readily understood by physicists, to retard the delivery or discharge of the contents of the drum or the substances passing therethrough via said intake and outlet tubes. Said hood has suitably fixed to its flat top portion a loop or eye 5, to which is to be attached or secured a line or rope 6, arranged to be under the control of the attendant of the machine whereby as he manipulates said rope the angle of presentation of the delivery end of said hood may be adjusted, as desired, through the aid of the pivotal connection between the hood and the tube-section already described.

Latitude is allowed as to details herein as circumstances suggest without departing from the spirit of our invention, and the latter will be protected.

We claim- 1. A stacker-hood for threshing-machines, having a bulged lateral portion, an intake or inlet tube delivering into said bulged lateral portion tangentially to the axial plane of said hood, and an outlet-tube member provided upon its inner surface with radial partitions.

2. A stacker-hood for threshing-machines, having its intake-tube pivoted to a tube-section, curtailed on curved lines at opposite points upon its rear edges, and means under the control of the attendant for effecting the adjustment of said hood from said tube-section.

3. A stacker-hood for threshing-machines, having an intake-tube and an outlet or delivery tube equipped upon its inner surface with radial partitions, for the purpose set forth.

4. A stacker-hood for threshing-machines, provided with a bulged lateral portion having a closed upper end, an intake or inlet tube delivering into said bulged lateral portion, tangentially to the axial plane of said hood and having a pivotal connection with a tube-section for tilting said hood vertically, and an outlet-tube member having upon its inner surface radial partitions.

In testimony whereof we have signed our names to this specification in the presence of two subscribing Witnesses.
